Actually there are currently 8 different logos:
Admittedly some are rather similar and can probably reuse some sub-files, but they clearly are not identical.
The list does not include ones that only appeared on very few parts and those from non-minifig themes such as Duplo, Jack Stone, Technic, Fabuland etc.
I am strongly in favour of using the years to mark them.
"Type x" is too arbitrary Imo and requires more knowledge than "I want to use the logo from 2 years ago". How many different ones were inbetween? Are the "Type x" even in the correct chronological order? Those problems are much less a thing when using years. Same can be applied to other things, Star Wars in particular.
Agree that there are some errors in the current parts (especially the older ones).
EDIT:
Here's quick overview of those logos (images taken from Bricklink.com):
- a) 1978-1993 (Legoland Town Era)
- b) 1994-2000 (System and Town Junior)
- c) 2004-2006 (World City and City)
- d) 2007-2011 (City)
- e) 2012 (Forest Fire)
- f) 2013-2018 (City)
- g) 2019-2021 (City Adventures)
